WATCH-MOVEMENT.

EBPECIPIGATION forming part of Letters Patent No. 324,689, dated August18, 1885.

Application filed July 19, 1884.

T 0 aZZ 107mm it may concern:

Be it known that I, GEORGE E. HART, of aterbnry, in the county of NewHaven, and in the State of Connecticut, have invented certain new anduseful Improvements in Watch- Moveineuts; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which Figure 1 is aperspective view of my movement from the dial side, said dial beingremoved. Fig. 2 is an enlarged perspective view of the seconds arbor andits connecting mechanism, and Fig. 3 is a section upon line as a: ofFig. 1.

Letters of like name and kind refer to like parts in each of thefigures.

The design of my invention is to enable a s conds-hand to be applied towatches which from their construction have heretofore been without thesame, to which end said invention consists, principally, in awatch-train in which a seconds-arbor and pinion are placed between andjournaled wholly within the sections of a'pillar-plate that are unitedupon a plane which is parallel with the faces of said plate,substantially as and for the purpose hereinafter specified.

It consists, further, in a watch-train in which the seconds-arbor isjournaled wholly within the pillar-plate, and is driven by means of atoothed wheel or pinion upon the contiguous end of an adjacent arbor,sub stantially as and for the purpose hereinafter shown.

In the annexed drawings, A represents the top plate, and B thepillar-plate, of a watch, which parts are connected together and held inrelative position by means of pillars C in the usual manner.

Between the plates A and B is journaled a time-train, of which the arbord of the third wheel, D, is located at one side of the lower center ofthe dial, and has its journal within the pillanplate B extend into acircular recess, I), which is provided in the outer face of said plate,and upon said projecting journal has secured a toothed wheel, E.

The whole or a part of the pillar-plate B is made sectional and itssections united upon a plane which is parallel with the faces of saidplate, and within such sections is journaled a seconds-arbor, f, uponwhich, between said sections, is a toothed wheel, F, that engages withthe wheel E and receives motion from the same. Upon the outer end ofsaid arbor f is a secondshanthf, which indicates seconds upon asuitably-divided dial. The seconds-arbor, being wholly within thepillar-plate,in no manner interferes with the other portions of thetime-train, and can be readily applied to any style of watch and can bedriven from any one of the arbors of such train by properlyproportioning the connecting toothed wheels upon the driving-arbor andsaid seconds-arbor. Should the arbor selected for actuating saidseconds-arbor revolve in the i wrong direction,an intermediate wheelwill be required for producing the correct motion of the seconds-hand.

Having thus fully set forth the nature and merits of my invention, whatI claim as new is 1. A watch-train in which a seconds-arbor and pinionare placed between and journaled wholly within the sections of apillar-plate that are united upon a plane which is paral- 101 with thefaces of said plate, substantially as and for the purpose specified.

2. A watch-train in which the seconds-arbor is journaled wholly withinthe pillarplate and is driven by means of the toothed wheel or pinionupon the contiguous end of an adjacent arbor, substantially as andforthe purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this15th day of March, 1884..
